lhiiiir wention relates to carriers for use in pneumatic dispatch apparatusrand more particularly to identification meansused' 1n qonnectioniwiththecarriers. V V Thecarriers referred to are of. that general 1 class made up of inner andouter shells movable with relation to each other; to bring accesseope nings; in the shells, into or out f alinQd relat on. The: principal feature of the; invention consists in. the use of interchangeable ,markersvfitting into, sight, opener ings formed for the purpose, in the outer shell and held inposition therein *by the engagement therewith of the outer surface of the inner shell.

section to larger scale on the which are loosely fitted together so that; I

they, can beeasil'y rotated relatively to one another to bring theaccess openings 7 and 8 therein into orf outof; alinement. Each one of these shells carries the usual terminal buffer 9.: formed of felt or other resilient materialy A stop or limiting member 17 may, beconueniently carried, by one offlthe shells for engagement with complementary recesses formed in the other shell to limit: relative rotation of the shellsin either diion, a

In order tofcause each carr-iento-display an identifying marker character individual to,the carrier, a sight opening 13 isv provided in the-outer Sh6l16 which takes the form of a preforation therethrough and in which is displayed the desired mark or: character. The identifying mark is preferably borne y & ection 14 ofsheets material sufficiently thin to permit it to occupythe restricted space between the tWOShQlISLWlthOHtI interference with the relative rotation thereof. In order tozregisterthe indentify-ing-mark with the. sight opening 13 portions .ofvthe:

ltgfl gfitethee ge Qfithea sight'opening and tion 16 would hear the designating characters as will be clear. A like effect may be obtained by reducing the thickness of a section of sheet material on one surface along the edge leaving a relatively thicker central portion substantially fitting the sight open ing and bearing the identifying characters.

I preferably make use of metal as a material from which to construct the markers although other material such as celluloid may be used if desired. It will be seen that the identifying marker of any given carrier receptacle may be removed and another marker substituted therefor by merely separating the two shells for which provision is made as follows: The shells not only are capable of relative rotational or angular movement as has been described but they are also capable of movement longitudinally by a telscoping action. The shells are normally restrained from such movement by the engagement of a suitable stop lug, preferably the aforesaid member 17, with an abutment element of the other shell, for example with the inner edge 17 of the sight opening 7. In order to bringrabout the longitudinal or axial separation referred to a recess orindented channel 19 in the inner shell is brought into axial alinement with the stop lug by relative rotation of the shells. Separation of the shells longitudinallycan then be effected as will be clear whereby an interchange of markers may be effected.

It will be clear that in the arrangement described a marking device is made use of which is always in sight regardless of the relative position of the shells, which does not require means for holding it in place other than the relation of the shells themselves, and which does not extend outwardly beyond the peripheral surface of the outer shell. i v

What I claim is 1. A pneumatic carrier comprising concentric cylindrical hollow rotatable shells each having a fixed head at one end, said,

shells having access openings in their side walls adapted to be moved into and out of registry by relative rotation of the shells, the outer shell also having a sight opening in its side wall, and an identifying-marker bearing against the outersurface of the inner shell and observable through the sight opening in the outer shell.

2. A pneumatic dispatch carrier comprising apair of relatively rotatable inner and outershells, said shells having openings respectively in their side walls adapted to be moved into or out of registry'byrelative rotation of the shells, the outer shell also having a sight opening in its side wall, and an identifying marker formed of relatively thin material disposed between the opposed 1 surfaces of the shells without interfering with the relative rotation of the Sl18lls,-said marker being visible through the sight opening in the outer shell.

3. In a pneumatic dispatch carrier com prising, including a pair of relatively rotatable inner and outer shells, an interchangeable identifying marker formed of marker formed of relatively thin material adapted to occu 3y a position between the confronting surfaces of the shells without interference Wit-h the relative rotation thereof, the outer shell being provided with a sight opening through which the marker is displayed, and means carried by the marker arranged to enter the sight opening and retain the marker in registration therewith.

5. A pneumatic dispatch carrier compris ing a pair of relatively rotatable inner and outer shells, an interchangeable identifying marker formed of relatively thin material adapted to occupy a position between the confronting surfaces of the shells, the outer shell being provided with a sight opening through which the marker is displayed, and raised protuberances on the marker arranged to enter the sight opening and retain the markerin registration therewith.

"6. A pneumatic dispatch carrier com.

prising a pair of relatively rotatable inner and outer shells, an interchangeable identifying marker formed of relatively thin material adapted to occupy a position between the confronting surfaces of the shells, the outer shell beingprovided with a sight opening-through which the marker is displayed, and the marker being so formed that a port-ion thereof enters the sight opening and retains the marker in registration therewith.

7 A pneumatic dispatch carrier comprising concentric relatively rotatable cylindrical shells, said shells having access openings adapted to bemoved into and out of registry by relative rotation of the shells; one of said shells also having a sight opening in its side wall, and a label interposed be tween the shells and visible through the pening,'the shells being separable to permit insertion or removal of the label.

8. A- pneumatic dispatch carrier comprising concentric relatively rotatable cylindricalshells, said shells having access openings adapted-tobe moved into and outof registry'by relative rotation of the shells; one of said shells also having a sight opening in its Side wall, a label interposed between the shells and visible through the sight opening, portions of the label underlying the edges of the opening to prevent its removal therethrough, and means normally operative to prevent relative axial movement of the shells but adapted to allow axial separation of the shells whereby to permit insertion or removal of the label. I

9. A pneumatic dispatch carrier comprising relatively rotatable concentric shells, having access openings adapted to be moved into and out of registry by relative rotation of the shells, one of said shells also having a sight opening, a removable label visible through said opening, said label having parts inter osed between the opposed faces of the shel s to prevent its escape through the opening, said shells being movable axially with respect to each other to permit their separation for the insertion and removal of the label, and disengageable elements carried by the respective shells normally preventing such axial separation.

V 10. A pneumatic dispatch carrier comprising relatively rotatable telescoping shells, said shells having registrable access openings in their peripheral walls, and means operative in all but one angular position of said shells to prevent axial separation of the shells, said means automatically becoming inoperative when the shells are'turned' relatively to one another to occupy said one angular position. 7 V

11. A pneumatic dispatch carriercomprising relatively rotatable telescoping cylindrical shells of substantially equal length and having access openings in their peripheral walls, and normally engagingparts carried by the respective shells adapted to prevent axial separation of the shells, said parts automatically becoming disengaged when the 12. A pneumatic dispatch carrier oompris- I mg relatively rotatable inner and outer shells having access openlngs 1n their peripheral walls, a stop lug projecting from one shell and normally engaging a part of the other shell to prevent axial separation of the shells, said stop lug being disengaged from said part when the shells are turned relatively to each other into a predetermined position thereby permitting free axial separation of the shells.

18. A pneumatic dispatch carrier comprising relatively rotatable telescoping shells, each shell having an access opening in its side wall, said openings being adapted to be brought into registry by relative rotation of the shells, and a rigid stop lug projecting from one shell and engaging the other shell normally to preventaxial separation of the shells, the latter shell having an axially extending channel through which the lug may pass when the shells occupy one predetermined angular position.

14. A pneumatic dispatch carrier comprising relatively rotatable telescoping cylindrical shells, the respective shells havingaccess openings in their walls which may be brought into and out of registry by relative rotation of the shells, and a stop member projecting from. one shell engaging an abutment element of the other shell normally to prevent axial'movement of the shells, said abutment element having a way there-' through adapted to permit the passage of said stop and the axial separation of the shells when the latter occupy a predetermined angular relationship.
